TE Connectivity 1546211-3 Terminal Block Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1546211-3 is a 3-position terminal block header with male pins, shrouded on 4 sides, featuring 0.197" (5.00mm) pitch vertical through-hole mounting. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing design and procurement requirements. The part operates at 15 A (UL) and 300 V (UL) with an operating temperature range of -40°C to 110°C. Substitution is required due to the obsolete product status while maintaining electrical and mechanical compatibility with existing circuit designs.

Direct Equivalent Category: Parts with identical pitch (0.197" / 5.00mm), 4-side shrouding, and matching electrical ratings constitute direct equivalents. The TE Connectivity 1776146-3 is the active direct equivalent from the same manufacturer.

Compatible Substitute Category: Parts with pitch tolerance of 0.200" (5.08mm) instead of 0.197" (5.00mm) are classified as compatible substitutes. This minor pitch variation (0.03mm difference) is within standard PCB layout tolerances for terminal block applications. These include Molex 0395311003, HARTING 14120317001000, and Phoenix Contact 1924318.

Partial Compatibility Category: Parts with 2-side shrouding (Molex 0395310003) or reduced current ratings (Phoenix Contact 1755529 at 12 A) are listed as partial compatibility options where mechanical or electrical constraints permit.

Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 1776146-3

The TE Connectivity 1776146-3 is the direct active equivalent to the obsolete 1546211-3. This part maintains identical electrical specifications (15 A UL, 300 V UL), mechanical configuration (3-position, 0.197" pitch, 4-side shrouded, vertical through-hole), and operating temperature range (-40°C to 110°C). The primary difference is housing color (black versus gray) and active product status with RoHS compliance. This part is the preferred substitution for direct replacement in existing designs.

Secondary Recommendations: Molex 0395211003 and HARTING 14120316001000

Both parts maintain the 0.197" (5.00mm) pitch specification and 4-side shrouding configuration. Molex 0395211003 operates at -40°C to 105°C (5°C lower maximum than the original). HARTING 14120316001000 provides enhanced voltage rating (600 V UL versus 300 V UL) and maintains the full -40°C to 110°C temperature range. Both are active products with current RoHS3 compliance.

Compatible Alternatives: Molex 0395311003, HARTING 14120317001000, Phoenix Contact 1924318

These parts feature 0.200" (5.08mm) pitch instead of 0.197" (5.00mm), representing a 0.03mm difference per position. This pitch variation is within standard PCB layout tolerances for terminal block applications. All three maintain 4-side shrouding, 15-16 A current ratings, and 300 V minimum voltage ratings. HARTING and Phoenix Contact parts support the full -40°C to 110°C operating temperature range.

Partial Compatibility Options: Molex 0395310003, Phoenix Contact 1755529 and 1755749

Molex 0395310003 features 2-side shrouding instead of 4-side, reducing EMI shielding. Phoenix Contact 1755529 and 1755749 operate at reduced current ratings (12 A versus 15 A). These parts are suitable only where design constraints permit reduced performance specifications.

Compliance Considerations

All active substitute parts carry RoHS3 compliance certification. The original 1546211-3 is marked as "Not applicable" for RoHS status due to its obsolete classification. All substitute parts maintain UL94 V-0 flammability rating and tin contact mating finish. ECCN and HTSUS classifications are consistent across all parts (EAR99 and 8536.69.4040 respectively).

Frequently Asked Questions (FAQ)

Q: Can I use the TE Connectivity 1776146-3 as a direct replacement for the 1546211-3?

A: Yes. The 1776146-3 is the active direct equivalent. It maintains identical electrical ratings (15 A UL, 300 V UL), mechanical configuration (3-position, 0.197" pitch, 4-side shrouded, vertical through-hole), and operating temperature range (-40°C to 110°C). The housing color differs (black versus gray), but this does not affect electrical or mechanical function.

Q: What is the significance of the 0.197" versus 0.200" pitch difference?

A: The 0.197" (5.00mm) pitch is the original specification. The 0.200" (5.08mm) pitch represents a 0.03mm difference per position. For a 3-position header, this totals approximately 0.06mm across the entire connector width. This variation is within standard PCB layout tolerances for terminal block applications and does not prevent mechanical or electrical compatibility in most designs.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts listed carry RoHS3 compliance certification. The original 1546211-3 is marked as "Not applicable" due to its obsolete status. If RoHS compliance is a design requirement, all listed active substitutes meet this specification.

Q: What is the difference between 4-side and 2-side shrouding?

A: 4-side shrouding provides EMI shielding on all four sides of the connector. 2-side shrouding provides shielding on only two sides. The original 1546211-3 features 4-side shrouding. Molex 0395310003 features 2-side shrouding and is suitable only where reduced EMI protection is acceptable.

Q: Can I use Phoenix Contact parts with 12 A or 16 A ratings instead of the original 15 A?

A: Phoenix Contact 1755529 and 1755749 operate at 12 A (below the original 15 A specification) and are suitable only where circuit current requirements do not exceed 12 A. Phoenix Contact 1924208 and 1924318 operate at 16 A (above the original 15 A specification) and provide additional current margin. Selection depends on actual circuit current requirements.

Q: What is the operating temperature range for Phoenix Contact substitutes?

A: Operating temperature data is not provided for Phoenix Contact parts 1755529, 1755749, 1924208, and 1924318 in the available specifications. The original 1546211-3 operates from -40°C to 110°C. TE Connectivity 1776146-3, Molex 0395211003 and 0395311003, and HARTING parts maintain documented operating temperature ranges of -40°C to 105°C or -40°C to 110°C.

Q: Are there any differences in contact material between substitutes?

A: The original 1546211-3 uses copper alloy contacts. Molex parts (0395211003, 0395310003, 0395311003) use brass contacts. HARTING parts use copper alloy. Phoenix Contact parts do not specify contact material in the available data. All parts use tin contact mating finish. Brass and copper alloy contacts are functionally equivalent for this application.

Q: What packaging options are available?

A: The original 1546211-3 packaging is not specified. All active substitute parts are available in bulk packaging. Inventory availability ranges from 812 to 15,258 pieces across the substitute options.
