Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 68683-236LF is determined by strict alignment of core electrical and mechanical parameters. The primary substitution criteria are:

Critical Matching Parameters:

• Connector type: Receptacle
• Number of positions: 72
• Pitch - mating: 0.100" (2.54mm)
• Number of rows: 2
• Row spacing - mating: 0.100" (2.54mm)
• Mounting type: Through hole
• Termination: Solder
• Fastening type: Push-pull
• Insulation height: 0.276" (7.00mm)
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)

The identified substitute parts, Mill-Max Manufacturing Corp. models 803-43-072-10-001000 and 803-93-072-10-001000, satisfy all critical matching parameters. Both substitute parts maintain identical mechanical footprints, electrical interface specifications, and environmental ratings required for direct board-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both Mill-Max substitute parts maintain active product status and comply with current regulatory requirements. The 803-43-072-10-001000 and 803-93-072-10-001000 are ROHS3 compliant, exceeding the RoHS compliance level of the primary part. Both substitute connectors provide identical mechanical interface compatibility and environmental performance specifications.

Selection between the two Mill-Max alternatives depends on post-contact finish requirements. The 803-43-072-10-001000 features tin post finish, while the 803-93-072-10-001000 features tin-lead post finish. Both maintain UL94 V-0 flammability ratings and unlimited moisture sensitivity classification.

The substitute parts exhibit slightly extended contact post length (0.118" versus 0.115") and operate across a narrower low-temperature range (-55°C minimum versus -65°C minimum). These dimensional and thermal variations remain within acceptable tolerance for standard board-to-board applications.

Frequently Asked Questions (FAQ)

Q: Are the Mill-Max 803 series connectors mechanically compatible with the Amphenol ICC 68683-236LF?

A: Yes. Both substitute parts maintain identical pitch (0.100"), row count (2), row spacing (0.100"), insulation height (0.276"), and through-hole solder termination. The connectors are mechanically interchangeable at the board level.

Q: What is the difference between the two Mill-Max substitute parts?

A: The primary difference is post-contact finish. The 803-43-072-10-001000 uses tin post finish, while the 803-93-072-10-001000 uses tin-lead post finish. Both maintain identical electrical and mechanical specifications otherwise.

Q: Does the extended contact post length on the Mill-Max parts affect compatibility?

A: The Mill-Max parts feature 0.118" post length compared to 0.115" on the Amphenol part. This 0.003" difference is within standard PCB through-hole tolerance and does not affect functional compatibility.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both Mill-Max parts are ROHS3 compliant, which exceeds the RoHS compliance status of the primary part.

Q: What is the operating temperature difference between the main part and substitutes?

A: The Amphenol ICC 68683-236LF operates from -65°C to 125°C, while both Mill-Max substitutes operate from -55°C to 125°C. The upper temperature limit is identical; the substitutes have a 10°C higher minimum operating temperature.

Q: Can I use these connectors in automotive applications?

A: The primary part is specified for automotive applications. The Mill-Max substitute parts do not list automotive applications in their specification data. Application suitability should be confirmed against specific automotive qualification requirements.

Q: What are the current ratings for these connectors?

A: The Amphenol ICC 68683-236LF does not specify a current rating. Both Mill-Max substitutes are rated for 4.5A per contact.
