ISS1-03 Equivalent & Substitute Parts

Part Overview

The ISS1-03 is a 3-position rectangular connector housing manufactured by Samtec Inc. as part of the Micro Mate™ ISS1 series. This connector housing is designed for free-hanging, in-line applications with crimp-style female socket contacts at 1.00mm pitch. The part is actively produced and ROHS3 compliant, making it suitable for modern electronic assemblies. Substitute parts may be required due to color availability, fastening mechanism preferences, or regional inventory constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISS1-03 is determined by the following critical parameters that must remain constant:

• Number of Positions: 3
• Pitch: 0.039" (1.00mm)
• Contact Type: Female Socket
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Insulation Material: Polyamide (PA), Nylon
• Number of Rows: 1
• Series: Micro Mate™ ISS1

The ISS1-03-L qualifies as a direct substitute because it maintains all critical electrical and mechanical parameters. Variations in color (Black vs. Natural) and fastening type (standard vs. Latch Lock) do not affect the core connector functionality and are acceptable substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

Both ISS1-03 and ISS1-03-L are active products with identical ROHS3 compliance and MSL ratings. Selection between these parts should be based on:

• Color requirement: ISS1-03 provides Black housing; ISS1-03-L provides Natural housing
• Fastening mechanism: ISS1-03-L includes Latch Lock fastening, while ISS1-03 does not specify a fastening type

Both parts maintain full compatibility with Micro Mate™ ISS1 series contacts and mating connectors. No performance degradation occurs when substituting between these parts for applications where color and fastening type are not design-critical constraints.

Frequently Asked Questions (FAQ)

Q: Can ISS1-03-L be used as a direct replacement for ISS1-03?

A: Yes. Both parts maintain identical electrical and mechanical specifications including position count, pitch, contact type, and termination method. Differences in color and fastening type do not affect connector functionality.

Q: What is the significance of the Latch Lock fastening on ISS1-03-L?

A: The Latch Lock fastening mechanism on ISS1-03-L provides additional mechanical retention compared to the standard fastening on ISS1-03. This feature does not affect electrical performance but may be preferred in applications requiring enhanced mating security.

Q: Are contacts included with these housings?

A: No. Both ISS1-03 and ISS1-03-L are housings only. Contacts must be sourced separately and crimped into the housing.

Q: Do color differences affect electrical performance?

A: No. The color difference between Black (ISS1-03) and Natural (ISS1-03-L) is purely cosmetic and does not impact electrical characteristics or compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both ISS1-03 and ISS1-03-L are ROHS3 compliant with MSL rating of 1 (Unlimited).
