Key Parameters

Substitute Part Grouping Explanation

The M80-8240645 can be substituted with the M80-7530645 based on the following critical parameters that determine functional compatibility:

• Connector Type: Both are headers with male pin contacts
• Number of Positions and Rows: Both feature 6 positions in 2 rows
• Pitch - Mating: Both maintain 0.079" (2.00mm) pitch spacing
• Row Spacing - Mating: Both maintain 0.079" (2.00mm) row spacing
• Mounting Type: Both are through-hole mounted
• Shrouding: Both feature shrouded 4-wall design
• Termination: Both use solder termination
• Fastening Type: Both use latch lock fastening
• Current Rating: Both rated at 2.2A
• Voltage Rating: Both rated at 800V
• Operating Temperature: Both operate from -55°C to 125°C
• Material Flammability Rating: Both meet UL94 V-0
• RoHS Status: Both are ROHS3 compliant

The primary differences are in contact post length (0.370" vs. 0.177"), insulation height (0.213" vs. 0.219"), insulation material (Polyamide PA46 vs. Polyphenylene Sulfide PPS), and product status (obsolete vs. active).

Parameter Comparison

Engineering Selection Recommendations

The M80-7530645 is the direct substitute for the obsolete M80-8240645. Both components are manufactured by Harwin Inc. within the same Datamate L-Tek series and maintain identical electrical and mechanical specifications for mating pitch, row spacing, contact configuration, current and voltage ratings, and operating temperature range.

The M80-7530645 is currently in active production status with confirmed inventory availability, whereas the M80-8240645 is obsolete. The substitute part carries identical compliance certifications: ROHS3 compliant, REACH unaffected, and UL94 V-0 flammability rating.

The primary design difference is the contact post length: the M80-8240645 features 0.370" (9.40mm) posts, while the M80-7530645 features 0.177" (4.50mm) posts. The insulation material differs (Polyamide PA46 versus Polyphenylene Sulfide PPS glass-filled), and the insulation height varies slightly (0.213" versus 0.219"). These differences do not affect electrical performance or mating compatibility when used with corresponding receptacle connectors designed for the Datamate L-Tek series.

Frequently Asked Questions (FAQ)

Q: Can the M80-7530645 directly replace the M80-8240645 in existing designs?

A: The M80-7530645 is electrically and mechanically compatible with the M80-8240645 for all standard mating applications. Both connectors maintain identical pitch spacing, contact configuration, and electrical ratings. The shorter contact post length of the M80-7530645 (4.50mm versus 9.40mm) requires verification that the mating receptacle or cable assembly is designed to accommodate this dimension. Consult the receptacle connector specifications to confirm compatibility.

Q: What is the significance of the insulation material change from Polyamide to Polyphenylene Sulfide?

A: Both insulation materials meet the same UL94 V-0 flammability rating and operate across the identical temperature range (-55°C to 125°C). Polyphenylene Sulfide (PPS) glass-filled material offers enhanced chemical resistance and dimensional stability compared to Polyamide PA46. This material change does not affect electrical performance or standard connector functionality.

Q: Are there any compliance or certification differences between these parts?

A: Both the M80-8240645 and M80-7530645 carry identical compliance certifications: ROHS3 compliant, REACH unaffected, and UL94 V-0 material flammability rating. Both are classified under ECCN EAR99 and HTSUS 8536.69.4040. No compliance differences exist between the two parts.

Q: Why is the M80-8240645 listed as obsolete?

A: The M80-8240645 is obsolete and no longer in production. The M80-7530645 serves as the active production equivalent within the Datamate L-Tek series. For new designs and ongoing procurement, the M80-7530645 is the recommended component.

Q: What are the mated stacking heights for these connectors?

A: Both the M80-8240645 and M80-7530645 support identical mated stacking heights: 7.23mm, 7.85mm, 10.2mm, and 14.61mm. These heights depend on the specific receptacle connector used in the mating pair.
