ELFH03190 Terminal Block Header Equivalent & Substitute Parts

Part Overview

The ELFH03190 is a 3-position vertical terminal block header manufactured by Amphenol PCD. This component features male pins with 2-side shrouding, 0.197" (5.00mm) pitch, and solder termination for through-hole mounting. The part is active in production with 1070 units in current inventory. Terminal block headers of this type are essential interconnection components in industrial control systems, power distribution modules, and signal routing applications where reliable electrical connections and mechanical stability are required. Equivalent and substitute parts may be necessary due to supply constraints, design revisions, or application-specific requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH03190 is determined by the following critical parameters: header type (male pins with 2-side shrouding), mounting orientation (vertical through-hole), termination method (solder), and electrical ratings (voltage and current capacity). The substitute parts are grouped based on compatibility with these core specifications.

Primary Substitutes (Full Compatibility): Parts 1753453 and 1758021 maintain identical position count (3), shrouding configuration (2-side), orientation (vertical), and termination style (solder). These parts operate within the same voltage class (300 V UL) and meet equivalent flammability standards (UL94 V-0).

Secondary Substitutes (Position Count Variation): Parts 1758018 (2-position) and 1758063 (7-position) share the same header type, shrouding, orientation, and termination characteristics but differ in position count. These are suitable only for applications where the specific position count is not a design constraint.

Key Substitution Parameters:

• Header type and shrouding configuration
• Vertical through-hole mounting
• Solder termination
• UL voltage rating (300 V minimum)
• UL94 V-0 flammability compliance
• Position count (where applicable)
• Pitch tolerance (5.00mm vs. 5.08mm)

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (1753453, 1758021): Parts 1753453 and 1758021 are functionally equivalent to the ELFH03190 for applications requiring 3-position terminal block headers. Both maintain active product status, meet UL94 V-0 flammability requirements, and comply with RoHS3 standards. Part 1753453 operates at the same 5.00mm pitch as the main part. Part 1758021 uses a 5.08mm pitch, which introduces a minor dimensional variation. Selection between these options depends on PCB layout constraints and mechanical fit requirements.

Position-Variant Substitutes (1758018, 1758063): Part 1758018 (2-position) and part 1758063 (7-position) are suitable only for applications where the position count differs from the original design. These parts share identical electrical ratings, flammability compliance, and mounting characteristics. All substitute parts from Phoenix Contact operate at 12 A UL current rating, which is lower than the ELFH03190's 15 A rating. Applications requiring the full 15 A capacity must use the original ELFH03190 or confirm that 12 A is acceptable for the intended circuit.

Compliance Considerations: All substitute parts maintain active production status and meet current regulatory requirements. The transition from RoHS to ROHS3 compliance in Phoenix Contact parts reflects current industry standards. Moisture sensitivity level (MSL 1) is consistent across all parts, indicating unlimited shelf life under standard storage conditions.

Frequently Asked Questions (FAQ)

Q: Can part 1753453 be used as a direct replacement for ELFH03190? A: Yes. Part 1753453 maintains the same 3-position count, 5.00mm pitch, vertical orientation, solder termination, and UL94 V-0 flammability rating. The primary difference is the 12 A UL current rating versus the ELFH03190's 15 A rating. Verify that 12 A is acceptable for your application.

Q: What is the difference between parts 1758021 and 1753453? A: Both are 3-position Phoenix Contact terminal block headers with identical electrical and flammability specifications. The key difference is pitch: 1758021 uses 0.200" (5.08mm) pitch while 1753453 uses 0.197" (5.00mm) pitch. This affects PCB footprint spacing and mechanical fit.

Q: Can I use part 1758018 (2-position) in place of ELFH03190 (3-position)? A: Part 1758018 is suitable only if your application requires fewer connection points. The 2-position configuration is not compatible with designs requiring 3 positions. All other electrical and mechanical characteristics are equivalent.

Q: Are there current rating limitations when substituting? A: Yes. The ELFH03190 is rated for 15 A at UL, while all Phoenix Contact substitutes (1753453, 1758018, 1758021, 1758063) are rated for 12 A at UL. Applications requiring the full 15 A capacity must use the original ELFH03190 or confirm that 12 A meets circuit requirements.

Q: Do all substitute parts meet the same compliance standards? A: All parts meet UL94 V-0 flammability requirements and are RoHS compliant. The ELFH03190 carries RoHS Compliant status, while Phoenix Contact parts carry ROHS3 Compliant status, reflecting current regulatory standards. Both designations are acceptable for new designs.

Q: What is the impact of pitch variation (5.00mm vs. 5.08mm)? A: Pitch variation affects PCB footprint spacing and mechanical alignment. Parts with 5.08mm pitch (1758018, 1758021, 1758063) have slightly wider spacing than the 5.00mm pitch parts (ELFH03190, 1753453). PCB layout must accommodate the specific pitch of the selected part.

Q: Which substitute part has the highest inventory availability? A: Part 1758018 (2-position) has the highest inventory with 14517 units in stock. For 3-position equivalents, part 1753453 has 2613 units and part 1758021 has 3718 units available.
