Substitute Part Grouping Explanation

The substitute part 0761557607 is classified as a direct equivalent based on the following criteria:

Electrical Parameters Match:

Identical number of positions (192)
Identical pitch spacing (0.053" / 1.35mm)
Identical contact layout (64 differential pairs)
Identical voltage rating (30V)
Identical contact finish and thickness

Mechanical Parameters Match:

Identical connector style (Impact, Guide Left)
Identical mounting configuration (Through Hole, Press-Fit)
Identical row and column arrangement (12 × 16)
Identical color (Black)

Compliance Parameters Match:

Identical flammability rating (UL94 V-0)
Identical operating temperature range (-55°C to 85°C)
Identical RoHS status (ROHS3 Compliant)
Identical moisture sensitivity level (MSL 1)

The primary distinction is product status: the original part is obsolete, while the substitute is active. Packaging differs (substitute supplied in Tray format), but this does not affect functional compatibility.

Engineering Selection Recommendations

The Molex 0761557607 is the direct substitute for the obsolete 0761556607. Selection is based on the following engineering criteria:

Product Status: The substitute part maintains active product status with Molex, ensuring continued availability and supply chain reliability. The original part's obsolete classification necessitates transition to the active equivalent.

Compliance Certification: Both parts maintain identical compliance certifications including ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity level. No additional qualification is required for regulated applications.

Electrical and Mechanical Compatibility: All functional parameters are identical, including connector geometry, contact configuration, pitch spacing, and termination method. Direct substitution is supported without circuit board redesign or connector interface modification.

Packaging Consideration: The substitute is supplied in Tray packaging format. Verify that receiving and handling procedures accommodate this packaging type for your production environment.

Frequently Asked Questions (FAQ)

Q: Can the 0761557607 be used as a direct replacement for the 0761556607 without PCB modification?

A: Yes. All electrical and mechanical parameters are identical. The connector interfaces, mounting footprints, and contact configurations match exactly. No PCB redesign is required.

Q: What is the primary reason for substitution?

A: The original part 0761556607 is classified as obsolete. The substitute 0761557607 is an active product with current manufacturing and supply availability.

Q: Are there any compliance or certification differences between the two parts?

A: No. Both parts maintain identical compliance status: ROHS3 compliant, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity level.

Q: Does the packaging format change affect component handling?
