Molex 0761550814 96-Position Impact Header Connector – Equivalent & Substitute Parts

Part Overview

The Molex 0761550814 is a 96-position male pin header connector in the Impact 76155 series, designed for through-hole PCB mounting with press-fit termination. This connector is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. The part features gold-plated contacts, UL94 V-0 flammability rating, and operates across -55°C to 85°C with a 30V voltage rating. Substitution is driven by product lifecycle management and the availability of active-status alternatives that maintain electrical and mechanical compatibility within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the Molex 0761550814 is based on the following critical parameters that must align for functional equivalence:

Primary Compatibility Criteria:

• Number of Positions: 96 (fixed requirement)
• Connector Type: Header, Male Pins (fixed requirement)
• Mounting Type: Through Hole (fixed requirement)
• Termination: Press-Fit (fixed requirement)
• Contact Finish: Gold (fixed requirement)
• Material Flammability Rating: UL94 V-0 (fixed requirement)
• RoHS Status: ROHS3 Compliant (fixed requirement)

Secondary Tolerance Parameters:

• Pitch: 0.053" (1.35mm) for direct equivalence; 0.075" (1.90mm) for mechanical/electrical substitution with footprint redesign consideration
• Operating Temperature Range: -55°C ~ 85°C minimum; extended ranges acceptable
• Voltage Rating: 30V minimum; higher ratings acceptable
• Contact Finish Thickness: 30.0µin (0.76µm) minimum; equal or greater acceptable

Substitute Categories:

1. Direct Equivalent (Same Pitch): Molex 0761551814 – identical electrical and mechanical specifications with active product status and improved packaging (Tray).

2. Cross-Manufacturer Substitutes (Different Pitch): TE Connectivity AMP Connectors Z-PACK TinMan series (1934303-1, 1934304-1, 1934305-1, 1934306-1) – maintain 96-position, male pin header, through-hole, press-fit configuration with higher voltage rating (250V) and current rating (0.5A), but feature 0.075" (1.90mm) pitch requiring PCB footprint modification.

Engineering Selection Recommendations

For Direct Replacement (No PCB Redesign Required):

Select Molex 0761551814 when maintaining the original 0.053" (1.35mm) pitch is mandatory. This part is the direct equivalent with identical electrical and mechanical specifications, active product status, and ROHS3 compliance. The transition from unspecified packaging to Tray packaging improves handling and storage efficiency without affecting connector performance.

For Cross-Manufacturer Substitution (PCB Footprint Modification Required):

TE Connectivity AMP Connectors Z-PACK TinMan series (1934303-1, 1934304-1, 1934305-1, 1934306-1) are functionally equivalent substitutes with the following considerations:

• All four TE parts maintain 96-position, male pin header, through-hole, press-fit architecture with gold contact finish and UL94 V-0 flammability rating.
• Pitch change from 0.053" (1.35mm) to 0.075" (1.90mm) requires PCB footprint redesign and revalidation.
• Extended operating temperature range (-65°C ~ 90°C) and elevated voltage rating (250V) provide enhanced performance margins over the original specification (30V).
• Specified current rating (0.5A) provides defined electrical performance where the original part does not specify this parameter.
• All TE parts are active-status products with established supply chains.
• Part 1934305-1 is designated for backplane connector usage, aligning with the original application category.

Selection Priority:

1. Molex 0761551814 for drop-in replacement scenarios.
2. TE Connectivity 1934305-1 for new designs or redesigns requiring cross-manufacturer substitution, given explicit backplane connector designation.
3. TE Connectivity 1934303-1, 1934304-1, or 1934306-1 as secondary alternatives when 1934305-1 is unavailable.

Frequently Asked Questions (FAQ)

Q: Can Molex 0761551814 be used as a direct replacement for Molex 0761550814?

A: Yes. Both parts share identical electrical and mechanical specifications: 96 positions, 0.053" (1.35mm) pitch, male pin header, through-hole mounting, press-fit termination, gold contact finish, UL94 V-0 rating, and ROHS3 compliance. The primary difference is product status (Active vs. Obsolete) and packaging format (Tray vs. unspecified). No PCB modifications are required.

Q: What is the primary limitation when substituting TE Connectivity parts for the Molex 0761550814?

A: The pitch differs: TE Connectivity Z-PACK TinMan series uses 0.075" (1.90mm) pitch versus the original 0.053" (1.35mm) pitch. This requires PCB footprint redesign, including via repositioning, trace routing adjustments, and mechanical clearance verification. Electrical and thermal performance must be revalidated after layout changes.

Q: Are TE Connectivity substitutes electrically compatible with the original design?

A: TE Connectivity parts exceed the original electrical specifications. The original 0761550814 specifies 30V voltage rating with unspecified current. TE parts provide 250V voltage rating and 0.5A current rating, offering enhanced performance margins. However, pitch modification necessitates PCB redesign and functional testing to confirm system-level compatibility.

Q: Which TE Connectivity part should be selected for backplane connector applications?

A: TE Connectivity 1934305-1 is explicitly designated for backplane connector usage, matching the original application category. Parts 1934303-1, 1934304-1, and 1934306-1 do not specify connector usage designation but maintain identical electrical and mechanical specifications.

Q: Do all substitute parts meet RoHS and MSL requirements?

A: Yes. Molex 0761551814 and all TE Connectivity substitutes (1934303-1, 1934304-1, 1934305-1, 1934306-1) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original part's compliance profile.

Q: What packaging formats are available for these connectors?

A: Molex 0761550814 (original) has unspecified packaging. Molex 0761551814 is supplied in Tray format. TE Connectivity parts (1934303-1, 1934304-1, 1934305-1, 1934306-1) are supplied in Tube format. Packaging selection affects handling, storage, and logistics but does not impact electrical or mechanical performance.

Q: Can the operating temperature range difference affect system performance?

A: TE Connectivity parts operate across -65°C ~ 90°C versus the original -55°C ~ 85°C. The extended lower temperature limit (-65°C vs. -55°C) and higher upper limit (90°C vs. 85°C) provide broader environmental tolerance. If the original design operates within -55°C ~ 85°C, TE parts will function within those parameters with additional margin.
