EDSTLZ975/2-SW Equivalent & Substitute Parts

Part Overview

The EDSTLZ975/2-SW is a 4-position terminal block header manufactured by On Shore Technology Inc., designed for 90° right-angle solder applications with 5.08mm pitch spacing. This component features male pins with dual-side shrouding and operates within a temperature range of -30°C to 105°C, rated for 300V UL voltage. The product is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where this connector type is required.

Substitute Part Grouping Explanation

Substitution eligibility for the EDSTLZ975/2-SW is determined by the following critical parameters:

Connector Type & Configuration: 4-position header with male pins and dual-side shrouding
Pitch Specification: 0.200" (5.08mm) center-to-center spacing
Orientation: 90° right-angle configuration
Electrical Rating: Minimum 300V UL voltage compliance
Mounting Interface: Solder termination capability
Compliance Standards: UL94 V-0 flammability rating and ROHS3 compliance

The substitute part 1762062 (Phoenix Contact COMBICON MDSTB series) meets these core substitution criteria through equivalent connector geometry, pitch alignment, voltage rating, and regulatory compliance. Differences in mounting method (through-hole vs. solder), housing material composition, and contact tail dimensions represent acceptable variations within the terminal block category while maintaining functional interchangeability for the specified application parameters.

Engineering Selection Recommendations

The EDSTLZ975/2-SW is classified as obsolete, necessitating transition to active production alternatives. The Phoenix Contact 1762062 serves as the primary substitute, offering active product status with equivalent electrical specifications (300V UL rating), matching connector geometry (4-position, 5.08mm pitch, 90° orientation), and identical flammability and RoHS compliance certifications.

Selection of 1762062 is supported by:

Active manufacturing status ensuring long-term availability
Identical pitch and position configuration enabling direct mechanical compatibility
Equivalent voltage and temperature operating parameters
Matching UL94 V-0 and ROHS3 compliance certifications
Dual-side shrouded male pin configuration maintaining the original connector type

The through-hole mounting method of 1762062 represents a functional variation from the solder termination of the original part. PCB layout modifications may be required to accommodate this mounting interface change. Contact tail length differential (0.138" vs. 0.126") is within acceptable tolerance for standard PCB through-hole spacing.

Frequently Asked Questions (FAQ)

Q: Can 1762062 be used as a direct replacement for EDSTLZ975/2-SW?

A: 1762062 provides functional equivalence for the core connector specifications: 4-position configuration, 5.08mm pitch, 90° right-angle orientation, 300V UL rating, and UL94 V-0 compliance. The primary design consideration is the mounting method transition from solder to through-hole, which requires PCB layout adaptation.

Q: What are the key compatibility factors for this substitution?

A: Compatibility is determined by pitch alignment (0.200"/5.08mm), position count (4), connector type (male pins, dual-side shrouded), voltage rating (300V minimum), and flammability certification (UL94 V-0). Both parts meet these criteria.

Q: Does the housing material difference affect performance?

A: The EDSTLZ975/2-SW uses polyamide (nylon) while 1762062 uses polybutylene terephthalate (PBT). Both materials meet UL94 V-0 flammability requirements and ROHS3 compliance. Material selection does not impact electrical performance within the specified operating temperature range (-30°C to 105°C).

Q: Are there dimensional considerations for PCB integration?

A: Contact tail length differs by 0.012" (0.30mm), which is negligible for standard PCB through-hole spacing. The transition from solder to through-hole mounting requires PCB pad pattern modification to accommodate the through-hole termination style.

Q: What certifications are maintained in this substitution?

A: Both parts maintain UL94 V-0 flammability rating, ROHS3 compliance, and REACH unaffected status. Electrical ratings (300V UL) are equivalent, ensuring regulatory and safety standard continuity.
