Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0713085540 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Matching Criteria:

• Connector type: Header, Breakaway
• Contact type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of positions: 40
• Number of rows: 2
• Row spacing - Mating: 0.100" (2.54mm)
• Mounting type: Surface Mount
• Termination: Solder
• Fastening type: Push-Pull
• Contact shape: Square
• Shrouding: Unshrouded
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)

The substitute parts listed (Amphenol ICC 95278-401A40LF and 95278-401B40LF) meet all primary matching criteria. Variations in contact length, insulation height, contact material, and contact finish thickness remain within acceptable engineering tolerances for board-to-board connector applications.

Parameter Comparison

Engineering Selection Recommendations

Both Amphenol ICC substitute parts (95278-401A40LF and 95278-401B40LF) are qualified as direct functional equivalents to the Molex 0713085540 based on matching electrical and mechanical specifications. All three parts maintain Active product status and comply with UL94 V-0 flammability requirements and MSL 1 moisture sensitivity classification.

The primary distinction between substitute options is packaging format: 95278-401A40LF is supplied in Cut Tape (CT) format, while 95278-401B40LF is supplied in Tube format. Selection between these two should be based on production assembly requirements and inventory management protocols.

Minor dimensional variations exist in contact length and insulation height between the Molex original and Amphenol ICC substitutes. These variations remain within acceptable tolerances for standard board-to-board connector applications and do not affect functional compatibility in typical circuit board designs.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine if a part can substitute for the Molex 0713085540?

A: The critical parameters are connector type (Header, Breakaway), contact type (Male Pin), pitch (0.100" / 2.54mm), position count (40), row configuration (2 rows), row spacing (0.100" / 2.54mm), mounting type (Surface Mount), termination method (Solder), and fastening type (Push-Pull). All substitute parts must match these specifications exactly.

Q: Are the Amphenol ICC parts fully compatible with the Molex original?

A: Yes. Both Amphenol ICC 95278-401A40LF and 95278-401B40LF meet all primary matching criteria for functional and mechanical compatibility. Minor variations in contact length (0.232" vs 0.240") and insulation height (0.100" vs 0.090") are within acceptable engineering tolerances for board-to-board applications.

Q: What is the difference between the two Amphenol ICC substitute parts?

A: The two Amphenol ICC parts are electrically and mechanically identical. The only difference is packaging: 95278-401A40LF is supplied in Cut Tape (CT) format, while 95278-401B40LF is supplied in Tube format. Selection depends on production assembly equipment and inventory management needs.

Q: Do all three parts have the same compliance certifications?

A: All three parts are UL94 V-0 rated and comply with RoHS standards. The Molex part is ROHS3 Compliant, while the Amphenol ICC parts are RoHS Compliant. All three maintain MSL 1 (Unlimited) moisture sensitivity classification.

Q: What is the difference in contact material between the parts?

A: The Molex 0713085540 uses Copper Alloy contacts, while the Amphenol ICC substitutes use Phosphor Bronze contacts. Both materials provide equivalent electrical performance and tin plating for solder compatibility in standard applications.

Q: Are there any temperature or current rating differences?

A: The Molex original does not specify operating temperature or current ratings in the provided data. The Amphenol ICC substitutes specify -65°C to 125°C operating temperature and 3A per contact current rating. These ratings indicate the Amphenol ICC parts are suitable for a defined operating envelope.
