Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 70232-126 are qualified based on the following critical parameters that determine functional compatibility:

• Number of Positions & Pitch: All substitutes maintain 24 positions at 0.079" (2.00mm) pitch, ensuring PCB footprint compatibility
• Mounting Configuration: Through-hole mounting with press-fit termination is preserved across all substitutes
• Electrical Ratings: Current rating of 1A and operating temperature range of -55°C ~ 125°C are maintained
• Contact Specifications: Gold plating at 30.0µin (0.76µm) thickness ensures consistent electrical performance
• Environmental Compliance: UL94 V-0 flammability rating and MSL 1 classification are consistent across all parts

The substitutes are grouped into two categories: direct manufacturer equivalents from Amphenol ICC and cross-manufacturer alternatives from TE Connectivity that meet the same functional requirements.

Parameter Comparison

Engineering Selection Recommendations

70232-126LF is the primary substitute for the obsolete 70232-126. Both parts are manufactured by Amphenol ICC within the Metral® series and share identical electrical and mechanical specifications. The 70232-126LF is currently in active production status with improved RoHS compliance and higher inventory availability (1050 pcs vs. 748 pcs). The LF designation indicates lead-free processing, making this part suitable for modern manufacturing environments requiring RoHS compliance.

5536514-1 from TE Connectivity AMP Connectors is a cross-manufacturer alternative that maintains all critical functional parameters: 24 positions, 0.079" (2.00mm) pitch, through-hole press-fit termination, and identical operating temperature range. This part is classified as ROHS3 compliant and carries active product status. The Z-PACK series designation and Futurebus connector style indicate this part is designed for similar backplane applications. Inventory availability is 874 pcs.

Selection between 70232-126LF and 5536514-1 depends on design requirements for connector style compatibility and supplier preference. Both parts satisfy the core electrical and mechanical requirements of the original 70232-126.

Frequently Asked Questions (FAQ)

Q: Can 70232-126LF be used as a direct replacement for 70232-126?

A: Yes. The 70232-126LF maintains identical electrical and mechanical specifications including position count, pitch, current rating, operating temperature range, and contact finish. The primary differences are product status (active vs. obsolete), RoHS compliance (compliant vs. non-compliant), and packaging (tube). The LF designation indicates lead-free processing.

Q: What are the key differences between 70232-126LF and 5536514-1?

A: Both parts share the same 24-position configuration, 0.079" (2.00mm) pitch, through-hole mounting, and operating temperature range. The primary differences are manufacturer (Amphenol ICC vs. TE Connectivity), connector series (Metral® vs. Z-PACK), and connector style (standard vs. Futurebus). The 5536514-1 specifies a 30V voltage rating not listed for the Amphenol parts.

Q: Are there any compliance differences between these substitutes?

A: Yes. The 70232-126 is RoHS non-compliant, while 70232-126LF is RoHS compliant and 5536514-1 is ROHS3 compliant. Both active substitutes meet modern environmental and regulatory requirements. REACH status differs: 70232-126LF is REACH Affected, while 5536514-1 is Vendor Undefined.

Q: What is the significance of the "LF" designation in 70232-126LF?

A: The LF designation indicates lead-free processing and RoHS compliance. This part is manufactured to eliminate lead and other restricted substances, making it suitable for applications requiring compliance with RoHS directives.

Q: Are the packaging formats interchangeable?

A: Both 70232-126LF and 5536514-1 are supplied in tube packaging. Packaging format does not affect electrical or mechanical compatibility; it only impacts handling, storage, and logistics considerations.

Q: What is the MSL rating and why is it relevant?

A: All three parts carry MSL 1 (Unlimited) classification, indicating unlimited shelf life without moisture absorption concerns. This simplifies storage and handling requirements compared to higher MSL ratings.
