Group 1 – Direct Molex Series Substitutes: The Molex 0761551635 is a direct equivalent within the Impact 76155 series. It maintains identical pitch (0.053"), configuration (12×16), voltage rating (30V), and temperature range (-55°C to 85°C). The only difference is packaging (Tray vs. standard) and active product status.

Group 2 – Cross-Manufacturer TE Connectivity Alternatives: Parts 1934315-1, 1934316-1, 1934317-1, and 1934318-1 from TE Connectivity are functionally equivalent but operate under different electrical parameters. These Z-PACK TinMan series connectors maintain 192 positions, through-hole mounting, and press-fit termination. However, they feature a larger pitch (0.075" / 1.90mm), higher voltage rating (250V), extended temperature range (-65°C to 90°C), and specified current rating (0.5A). These differences require mechanical and electrical design verification before substitution.

Engineering Selection Recommendations

Recommended Primary Substitute: Molex 0761551635

The Molex 0761551635 is the preferred direct replacement for the obsolete 0761550635. Both parts are electrically and mechanically identical, with matching pitch (0.053"), voltage rating (30V), temperature range (-55°C to 85°C), and RoHS3 compliance. The 0761551635 maintains active product status with higher inventory availability (1063 units vs. 930 units). Packaging differs (Tray vs. standard), but this does not affect functional compatibility.

Alternative Cross-Manufacturer Substitutes: TE Connectivity Z-PACK TinMan Series (1934315-1, 1934316-1, 1934317-1, 1934318-1)

The TE Connectivity parts are functionally equivalent for 192-position through-hole header applications but introduce design trade-offs:

Pitch increases from 0.053" to 0.075", requiring PCB layout modification
Voltage rating increases from 30V to 250V, providing design margin for higher-voltage applications
Temperature range extends from -55°C to 85°C to -65°C to 90°C
Current rating is specified at 0.5A, whereas the Molex part does not specify current

These differences are acceptable only if the target application can accommodate the larger pitch and does not require the original compact 0.053" spacing. All TE Connectivity variants maintain UL94 V-0 flammability rating, MSL 1 (Unlimited), and RoHS compliance.

Packaging Considerations:

Molex 0761551635: Tray packaging
TE 1934315-1, 1934317-1, 1934318-1: Tube packaging
TE 1934316-1: Bulk packaging

Packaging selection depends on assembly process requirements and inventory management protocols.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0761551635 be used as a direct drop-in replacement for the 0761550635?

A: Yes. Both parts share identical electrical and mechanical specifications: 192 positions, 0.053" pitch, 12×16 configuration, through-hole press-fit termination, 30V rating, -55°C to 85°C operating range, and UL94 V-0 flammability. The only difference is packaging format (Tray vs. standard) and product status (Active vs. Obsolete).

Q: What are the key differences between the Molex Impact series and TE Connectivity Z-PACK TinMan series?

A: The primary differences are pitch (0.053" vs. 0.075"), voltage rating (30V vs. 250V), temperature range (-55°C to 85°C vs. -65°C to 90°C), and current specification (unspecified vs. 0.5A). The larger pitch of the TE parts requires PCB layout modification and is not suitable for applications requiring the original compact spacing.

Q: Are all substitute parts RoHS compliant?

A: Yes. The Molex 0761551635 is ROHS3 compliant. The TE Connectivity parts are RoHS compliant, with 1934316-1 listed as RoHS Compliant and the remaining TE variants (1934315-1, 1934317-1, 1934318-1) as ROHS3 Compliant. All parts meet RoHS requirements.

Q: Which substitute part has the highest inventory availability?

A: TE Connectivity 1934318-1 has the highest inventory at 2240 units. Molex 0761551635 has 1063 units available.

Q: Can TE Connectivity parts be used in applications originally designed for the Molex 0761550635?

A: TE Connectivity substitutes are functionally equivalent for 192-position through-hole header applications but require design verification. The 0.075" pitch (vs. 0.053") necessitates PCB layout changes. The higher voltage rating (250V vs. 30V) and extended temperature range (-65°C to 90°C vs. -55°C to 85°C) provide additional design margin but do not prevent substitution if mechanical spacing can be accommodated.

Q: What is the MSL rating for all substitute parts?

A: All parts, including the main part and all substitutes, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations during storage or handling.
