Substitution Categories:

Direct Equivalent (Same Manufacturer): TE Connectivity 1-1776153-1 provides identical electrical and mechanical specifications with active product status. Housing color differs (black vs. green) but does not affect functional performance.
Cross-Manufacturer Equivalents (Weidmüller Omnimate SL Series): Parts 1629220000 and 1625340000 provide 4-side shrouded configurations matching the original specification. Parts 1629110000 and 1625120000 provide 2-side shrouded alternatives with pitch variations (7.50mm and 7.62mm respectively).

All substitute parts maintain UL94 V-0 flammability rating, copper alloy contacts, and 0.472" (12.00mm) insulation height. Pitch tolerance and shroud configuration differences require mechanical verification during board layout integration.

Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 1-1776153-1

The TE Connectivity 1-1776153-1 is the preferred direct substitute for the obsolete 1-282964-1. This part maintains identical electrical specifications (15 A at 300 V), mechanical configuration (11 positions, 0.295" pitch, 4-side shroud, vertical through-hole), and thermal operating range (-40°C to 110°C). The part carries active product status with RoHS compliance, ensuring long-term availability and supply chain stability. The only difference is housing color (black vs. green), which does not affect electrical or mechanical performance. This part is suitable for direct board-level substitution without design modification.

Secondary Recommendation: Weidmüller 1629220000

The Weidmüller 1629220000 provides a functionally equivalent 4-side shrouded configuration with matching 0.295" (7.50mm) pitch and 11-position count. This part exceeds the original specification with higher current rating (18.5 A per IEC) and voltage rating (800 V per IEC). The contact tail length is shorter (0.126" vs. 0.138"), requiring verification of PCB pad depth compatibility. Operating temperature range is -50°C to 100°C, which covers the original -40°C to 110°C specification except at the upper limit. This part is suitable for applications where the reduced upper temperature limit is acceptable.

Alternative Consideration: Weidmüller 1629110000

The Weidmüller 1629110000 provides a 2-side shrouded configuration with matching 0.295" (7.50mm) pitch. This part is suitable only if the application permits reduced shroud coverage. The shorter contact tail length (0.126" vs. 0.138") requires PCB verification. This part offers the same electrical performance as 1629220000 with active product status and RoHS compliance.

Not Recommended: Weidmüller Parts with 0.300" (7.62mm) Pitch

Parts 1625340000 and 1625120000 feature 0.300" (7.62mm) pitch, which differs from the original 0.295" (7.50mm) specification. These parts require mechanical re-qualification and PCB layout modification. Use only if board redesign is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-1776153-1 be used as a direct replacement for the 1-282964-1?

A: Yes. The 1-1776153-1 is a direct functional equivalent with identical electrical ratings (15 A, 300 V), mechanical configuration (11 positions, 0.295" pitch, 4-side shroud, vertical through-hole), and operating temperature range (-40°C to 110°C). The housing color difference (black vs. green) does not affect performance. No design modification is required.

Q: What is the difference between 4-side and 2-side shrouded terminal blocks?

A: Shroud configuration refers to the number of sides of the connector housing that are enclosed. 4-side shrouded provides complete enclosure on all four sides, offering maximum protection against accidental contact and cross-talk. 2-side shrouded provides enclosure on two opposing sides. The original 1-282964-1 is 4-side shrouded. Weidmüller parts 1629220000 and 1625340000 are 4-side shrouded equivalents; parts 1629110000 and 1625120000 are 2-side shrouded alternatives.

Q: Why do Weidmüller parts have different contact tail lengths?

A: The Weidmüller Omnimate SL series uses a contact tail length of 0.126" (3.20mm), compared to the TE Connectivity 0.138" (3.50mm). This difference requires verification of PCB pad depth and solder joint geometry during board layout. Consult PCB design guidelines and perform solder joint analysis if substituting with Weidmüller parts.

Q: Can I use a part with 0.300" (7.62mm) pitch instead of 0.295" (7.50mm)?

A: No, without board redesign. The pitch difference of 0.005" (0.12mm) per position accumulates across 11 positions, resulting in a total spacing error of approximately 0.055" (1.4mm). This exceeds typical PCB tolerance and will cause misalignment. Parts 1625340000 and 1625120000 with 0.300" pitch require PCB layout modification and re-qualification.

Q: Are all substitute parts RoHS compliant?

A: Yes. The main part 1-282964-1 is ROHS3 compliant. All substitute parts (TE Connectivity 1-1776153-1 and Weidmüller 1629220000, 1625340000, 1629110000, 1625120000) are RoHS compliant, meeting environmental and regulatory requirements.

Q: What is the difference in operating temperature between the main part and Weidmüller substitutes?

A: The original 1-282964-1 operates from -40°C to 110°C. Weidmüller parts operate from -50°C to 100°C. The Weidmüller range extends 10°C lower but is 10°C lower at the upper limit. For applications requiring operation above 100°C, the TE Connectivity 1-1776153-1 is required.

Q: What is the current and voltage rating difference between TE Connectivity and Weidmüller parts?

A: Both the main part and all substitutes meet the UL specification of 15 A at 300 V. Weidmüller parts additionally meet IEC specifications of 18.5 A at 800 V, providing higher performance margins. This does not affect compatibility; the UL ratings are the controlling specification for applications requiring UL certification.

Q: Is the TE Connectivity 1-1776153-1 available in the same green color as the original?

A: No. The 1-1776153-1 is available in black housing, while the original 1-282964-1 is green. Housing color is a cosmetic difference and does not affect electrical or mechanical performance. If color matching is required for assembly or identification purposes, Weidmüller parts are available in orange housing.

Q: Can I mix and match shroud configurations on the same board?

A: This depends on application requirements and board layout. If the application requires consistent shroud coverage for EMI shielding or safety, all positions should use the same shroud configuration. If shroud configuration is not critical to the application, 2-side and 4-side shrouded parts can coexist on the same board, provided pitch and electrical specifications are matched.
