Substitute Part Grouping Explanation

Substitute parts for the Molex 0761556804 are identified based on strict electrical and mechanical parameter matching within the Impact 76155 series. The substitution criteria are:

Identical number of positions (96)
Matching connector type (Header, Male Pins)
Identical connector style (Impact, Guide Left)
Same pitch specification (0.053" / 1.35mm)
Matching row and column configuration (12 × 8)
Identical mounting type (Through Hole)
Same termination method (Press-Fit)
Matching contact layout (32 Differential Pairs)
Identical contact finish and thickness (Gold, 30.0µin)
Same color (Black)
Matching voltage and temperature ratings
Equivalent compliance certifications (ROHS3, UL94 V-0)

The substitute parts 0761553804 and 0761557804 meet all these criteria and are classified as active products, providing direct functional equivalence to the obsolete 0761556804.

Engineering Selection Recommendations

Both substitute parts 0761553804 and 0761557804 are direct functional equivalents to the obsolete 0761556804. Selection between these active alternatives should be based on packaging requirements and inventory availability:

0761553804: Available in tray packaging with 785 units in stock
0761557804: Available in tray packaging with 728 units in stock

Both parts maintain identical electrical specifications, mechanical dimensions, and compliance certifications (ROHS3 Compliant, UL94 V-0). The choice between them depends on procurement logistics and packaging preferences for your assembly process. No electrical or mechanical re-qualification is required when substituting either part for the obsolete 0761556804 in existing designs.

Frequently Asked Questions (FAQ)

Q: Can I use 0761553804 or 0761557804 as direct replacements for 0761556804?

A: Yes. Both substitute parts are direct functional equivalents. They share identical electrical specifications, mechanical dimensions, pitch, row/column configuration, contact layout, and compliance certifications. No design modifications are required.

Q: What is the difference between the three part numbers?

A: The primary difference is product status. The 0761556804 is obsolete, while 0761553804 and 0761557804 are active products. All three parts are electrically and mechanically identical within the Impact 76155 series. The substitute parts differ only in packaging format (tray) and inventory availability.

Q: Are there any compatibility concerns when switching from 0761556804 to the substitute parts?

A: No compatibility concerns exist. The substitute parts maintain the same 96-position header configuration, 0.053" pitch, 12 × 8 row/column layout, through-hole mounting, and press-fit termination. PCB footprints and connector mating interfaces are identical.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. Both 0761553804 and 0761557804 are ROHS3 Compliant and carry UL94 V-0 material flammability ratings, matching the compliance profile of the original 0761556804.
