Substitute Part Grouping Explanation

The Molex 0761555806 qualifies as a direct substitute for the 0761554806 based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Identical connector position count (96 positions)
• Matching connector type and style (Header, Male Pins; Impact, Guide Right)
• Identical pitch specification (0.053" / 1.35mm)
• Matching row and column configuration (12 × 8)
• Identical contact layout (32 Differential Pairs)
• Same mounting and termination method (Through Hole, Press-Fit)
• Matching contact finish and thickness (Gold, 30.0µin)
• Identical operating temperature range (-55°C to 85°C)
• Same voltage rating (30V)
• Equivalent material flammability rating (UL94 V-0)
• Matching RoHS compliance status (ROHS3 Compliant)

The primary distinction between these parts is product status: the 0761554806 is obsolete, while the 0761555806 is active. The 0761555806 is supplied in Tray packaging, whereas the original part number does not specify packaging details.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0761555806 is the appropriate selection for applications currently using or requiring the 0761554806. The substitute part maintains full electrical and mechanical compatibility across all specified parameters. The 0761555806 carries active product status, ensuring availability and ongoing manufacturer support, whereas the original part number is obsolete and subject to supply discontinuation.

Both parts meet ROHS3 compliance requirements and carry identical UL94 V-0 material flammability ratings, satisfying regulatory requirements for applications in controlled environments. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for either part.

Selection of the 0761555806 eliminates obsolescence risk while preserving full functional equivalence for backplane connector applications requiring 96-position headers with Impact connector geometry and press-fit termination.

Frequently Asked Questions (FAQ)

Q: Are the 0761554806 and 0761555806 electrically interchangeable?

A: Yes. Both parts are rated for 30V operation, feature identical gold contact finish specifications (30.0µin thickness), and support the same 32 differential pair configuration. Electrical performance is equivalent across the specified operating temperature range of -55°C to 85°C.

Q: What is the primary reason to substitute the 0761554806?

A: The 0761554806 is classified as obsolete. The 0761555806 is an active product from the same manufacturer and series, providing assured supply and continued manufacturer support.

Q: Are there packaging differences between these parts?

A: The 0761555806 is supplied in Tray packaging. The original 0761554806 does not specify packaging details. Packaging differences do not affect electrical or mechanical compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and carry UL94 V-0 material flammability ratings. MSL rating is 1 (Unlimited) for both, indicating no moisture sensitivity constraints.

Q: Can the 0761555806 be used in existing PCB designs without modification?

A: Yes. The 0761555806 maintains identical mechanical dimensions, pitch (0.053" / 1.35mm), mounting type (Through Hole), and termination method (Press-Fit) as the original part. No PCB design changes are required.

Q: Are there any thermal or voltage derating considerations?

A: No. Both parts operate across the identical temperature range (-55°C to 85°C) and carry the same 30V voltage rating. No derating adjustments are necessary for the substitute part.
