EHT-110-01-S-D Equivalent & Substitute Parts

Part Overview

The EHT-110-01-S-D is an active rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 20-position, 2-row connector with 0.079" (2.00mm) pitch provides board-to-cable/wire connectivity with shrouded 4-wall construction and latch lock/eject fastening. Finding equivalent substitute parts may be necessary due to inventory availability, lead time considerations, or specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the EHT-110-01-S-D must maintain compatibility across the following critical parameters:

• Connector type (Header) and contact type (Male Pin)
• Position count (20) and row configuration (2 rows)
• Mating pitch and row spacing (0.079" / 2.00mm)
• Mounting method (Through Hole) and termination (Solder)
• Shrouding style (Shrouded - 4 Wall) and fastening mechanism (Latch Lock/Eject Hooks)
• Contact finish on mating surface (Gold)
• Insulation material (Liquid Crystal Polymer)
• Compliance certifications (ROHS3, UL94 V-0, MSL 1)

The 3M 155220-6302-RB meets these core substitution criteria while operating within the specified electrical and mechanical envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the EHT-110-01-S-D and 155220-6302-RB are active products with ROHS3 compliance and UL94 V-0 flammability ratings. The connectors share identical mating pitch, row configuration, shrouding, and fastening specifications, establishing mechanical and electrical compatibility for standard board-to-cable/wire applications.

The EHT-110-01-S-D supports a higher current rating of 3A and an extended upper operating temperature of 125°C. The 155220-6302-RB operates to 105°C maximum with a 1.25A current rating. Selection between these parts should be based on application current requirements and thermal environment specifications. Both parts maintain MSL 1 moisture sensitivity and identical contact finish specifications on mating surfaces.

Frequently Asked Questions (FAQ)

Q: Can the 155220-6302-RB directly replace the EHT-110-01-S-D in all applications?

A: The 155220-6302-RB is mechanically and electrically compatible for applications operating within its specified limits. Applications requiring currents above 1.25A or operating temperatures above 105°C must use the EHT-110-01-S-D.

Q: What are the dimensional differences between these connectors?

A: The 155220-6302-RB has a longer mating contact length (0.150" vs 0.120") and greater insulation height (0.425" vs 0.370"). Post contact lengths are similar (0.112" vs 0.114"). These differences may affect PCB layout and mating depth considerations.

Q: Are the insulation materials equivalent?

A: Both use Liquid Crystal Polymer (LCP) insulation. The 155220-6302-RB specifies glass-filled LCP, which provides enhanced mechanical properties. Both materials meet UL94 V-0 flammability requirements.

Q: Do packaging differences affect component selection?

A: The EHT-110-01-S-D is supplied in tube packaging while the 155220-6302-RB is supplied in tray packaging. Packaging selection depends on assembly process requirements and inventory management practices.

Q: Are both parts RoHS compliant?

A: Yes, both the EHT-110-01-S-D and 155220-6302-RB are ROHS3 compliant with MSL 1 moisture sensitivity level.
