Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0761550835 is determined by the following critical parameters:

• Connector Position Count: 96 positions (fixed requirement)
• Connector Type: Header with male pins (fixed requirement)
• Mounting Method: Through-hole PCB mounting (fixed requirement)
• Termination Style: Press-fit contact termination (fixed requirement)
• Contact Finish: Gold plating (fixed requirement)
• Flammability Rating: UL94 V-0 minimum (fixed requirement)
• RoHS Compliance: ROHS3 Compliant (fixed requirement)

Substitute parts are grouped into two categories:

Category 1: Direct Molex Series Continuation

• Part 0761551835: Active-status variant of the same Impact 76155 series with identical electrical and mechanical specifications. Differs only in packaging (Tray vs. standard).

Category 2: TE Connectivity Z-PACK TinMan Series (MFR Recommended)

• Parts 1934303-1, 1934304-1, 1934305-1, 1934306-1: High-speed backplane connectors with 96 positions, male pins, through-hole mounting, and press-fit termination. These parts maintain compatibility with the core mechanical interface while offering enhanced electrical performance characteristics (0.5A current rating, 250V voltage rating, -65°C to 90°C operating range).

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Series Continuation): Select Molex 0761551835 when maintaining the Impact 76155 series is required. This part is an active-status variant with identical electrical and mechanical specifications to the obsolete 0761550835. The only difference is packaging format (Tray). This option ensures no design modification is necessary.

For Enhanced Performance and Long-Term Support: Select one of the TE Connectivity Z-PACK TinMan series parts (1934303-1, 1934304-1, 1934305-1, or 1934306-1) when:

• Extended operating temperature range (-65°C to 90°C vs. -55°C to 85°C) is beneficial
• Higher voltage rating (250V vs. 30V) provides additional design margin
• Specified current rating (0.5A) is required for system documentation
• Long-term active product status and availability are priorities

All substitute options maintain ROHS3 compliance and UL94 V-0 flammability certification. The TE Connectivity variants are manufacturer-recommended alternatives with superior inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity Z-PACK TinMan series (1934303-1, 1934304-1, 1934305-1, 1934306-1) be used as a direct drop-in replacement for the Molex 0761550835?

A: These parts are mechanically and functionally compatible for 96-position through-hole backplane applications. However, the pitch differs (0.075" vs. 0.053"), which requires PCB layout verification. The TE parts offer enhanced electrical specifications (250V, 0.5A) compared to the Molex original (30V, unspecified current). Compatibility depends on your specific PCB design and electrical requirements.

Q: What is the difference between Molex 0761550835 and Molex 0761551835?

A: Both parts are from the Impact 76155 series with identical electrical and mechanical specifications. The primary difference is packaging: 0761550835 uses standard packaging, while 0761551835 is supplied in Tray format. The 0761551835 is active-status, making it the preferred choice for new procurements within the Molex Impact series.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The Molex 0761551835 and all TE Connectivity Z-PACK TinMan variants (1934303-1, 1934304-1, 1934305-1, 1934306-1) are ROHS3 compliant with UL94 V-0 flammability certification, matching the original part's compliance profile.

Q: Which substitute part should I select if my application requires the lowest operating temperature?

A: The TE Connectivity Z-PACK TinMan series supports -65°C minimum operating temperature, compared to -55°C for the Molex variants. Select any of the TE parts (1934303-1, 1934304-1, 1934305-1, or 1934306-1) if extended low-temperature operation is required.

Q: Do the TE Connectivity parts have different variants, or are 1934303-1, 1934304-1, 1934305-1, and 1934306-1 interchangeable?

A: All four TE Connectivity part numbers share identical electrical and mechanical specifications. They are functionally interchangeable for 96-position backplane header applications. Selection among these variants may be based on inventory availability or internal part numbering conventions.
