Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EB71D-SE3660X is determined by the following critical parameters:

• Position Count & Pitch: 72 positions at 0.156" (3.96mm) spacing
• Connector Type: Dual edge, female gender
• Contact System: Phosphor bronze with gold plating
• Termination Method: Solder attachment
• Electrical Performance: Dual read-out configuration
• Environmental Range: Operating temperature compatibility

The substitute part RMM36DRKH-S13 from Sullins Connector Solutions satisfies all mandatory substitution criteria. Both connectors maintain identical position counts, pitch spacing, contact material composition, and termination methodology. The substitute operates across -65°C to 125°C, which encompasses the original operating range. Both parts are classified as dual edge, female connectors with phosphor bronze contacts finished in gold.

Parameter Comparison

Engineering Selection Recommendations

The RMM36DRKH-S13 serves as a direct functional substitute for the obsolete EB71D-SE3660X. Both connectors maintain electrical and mechanical compatibility across all critical parameters. The substitute part offers the advantage of active product status, ensuring continued availability and supply chain stability. Additionally, the RMM36DRKH-S13 achieves ROHS3 compliance, whereas the original part is RoHS non-compliant, providing improved environmental and regulatory alignment for new designs or system upgrades.

The card thickness specification of the substitute (0.062" / 1.57mm) falls within the acceptable range of the original connector (0.054" ~ 0.071" / 1.37mm ~ 1.80mm), confirming mechanical compatibility. The extended lower operating temperature limit (-65°C versus -55°C) of the substitute provides additional thermal margin without compromising upper temperature performance.

Frequently Asked Questions (FAQ)

Q: Can RMM36DRKH-S13 be used as a direct replacement for EB71D-SE3660X?

A: Yes. Both connectors are 72-position female dual edge connectors with 0.156" pitch, phosphor bronze gold-plated contacts, and solder termination. All electrical and mechanical parameters align for direct substitution.

Q: What is the difference in card thickness tolerance between these connectors?

A: The EB71D-SE3660X accepts card thickness from 0.054" to 0.071" (1.37mm to 1.80mm). The RMM36DRKH-S13 is specified for 0.062" (1.57mm) cards, which falls within the original tolerance band, confirming compatibility.

Q: Does the RMM36DRKH-S13 support the same operating temperature range?

A: The substitute operates from -65°C to 125°C, which encompasses the original -55°C to 125°C range. The extended lower temperature capability provides additional margin.

Q: What is the significance of the RoHS compliance difference?

A: The EB71D-SE3660X is RoHS non-compliant, while RMM36DRKH-S13 is ROHS3 compliant. For new system designs or regulatory requirements, the substitute offers improved environmental compliance.

Q: Are there any mounting differences between these connectors?

A: The EB71D-SE3660X uses through-hole mounting. The RMM36DRKH-S13 employs board edge straddle mount termination. Both are solder-based attachment methods suitable for PCB integration.

Q: What is the contact finish thickness of the substitute part?

A: The RMM36DRKH-S13 specifies 30.0µin (0.76µm) gold contact finish thickness, providing defined plating specifications for reliability and wear resistance.
