OSTED033150 Equivalent & Substitute Parts

Part Overview

The OSTED033150 is a 3-position wire-to-board terminal block manufactured by On Shore Technology Inc., designed for horizontal mounting with 0.150" (3.81mm) pitch spacing and through-hole PCB installation. This component features screw-rising cage clamp termination suitable for 16-24 AWG wire gauges at 8 A and 300 V ratings.

The OSTED033150 carries an obsolete product status. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for applications requiring this terminal block configuration.

Engineering Selection Recommendations

Both EDZ602/3 and 1727023 are active-status alternatives to the obsolete OSTED033150. Selection between these substitutes depends on supply chain availability and manufacturer preference.

EDZ602/3 (On Shore Technology Inc.): Maintains original manufacturer continuity with identical pitch, orientation, and termination method. Supports extended wire gauge range (16-30 AWG) and higher current capacity (10 A). Identical operating temperature range and RoHS3 compliance ensure direct functional equivalence.

1727023 (Phoenix Contact COMBICON MKDS series): Provides equivalent electrical and mechanical specifications with higher current capacity (10 A) and extended wire gauge support (16-30 AWG). ROHS3 and MSL 1 compliance maintained. Operating temperature range not specified in available documentation.

Both parts satisfy all mandatory matching parameters and allowable variations. Selection should prioritize active inventory status and established supply relationships.

Frequently Asked Questions (FAQ)

Q: Can EDZ602/3 or 1727023 directly replace OSTED033150 in existing designs?

A: Yes. Both substitute parts maintain identical pitch spacing (0.150"), mating orientation (horizontal with board), mounting type (through-hole), and wire termination method (screw-rising cage clamp). PCB footprints and connector interfaces are compatible.

Q: What is the significance of the current rating increase from 8 A to 10 A?

A: The substitute parts support higher current capacity, which exceeds the original specification. This represents an improvement in electrical capability and does not create compatibility issues for applications operating at or below 8 A.

Q: Are there wire gauge compatibility considerations?

A: The OSTED033150 supports 16-24 AWG wire gauges. Both substitutes support 16-30 AWG ranges, which fully encompasses the original specification. Applications using 16-24 AWG wire are fully compatible with substitute parts.

Q: How do housing material differences affect substitution?

A: OSTED033150 uses thermoplastic housing; EDZ602/3 and 1727023 use polyamide (PA) nylon. Both materials provide equivalent mechanical and thermal performance for the specified operating temperature range (-30°C ~ 105°C). Material substitution does not affect functional compatibility.

Q: What packaging considerations apply to these substitutes?

A: OSTED033150 is supplied in standard packaging. EDZ602/3 and 1727023 are supplied in bulk packaging. Bulk packaging does not affect component specifications or performance; it reflects current manufacturing and distribution practices for active-status parts.

Q: Are RoHS and compliance certifications maintained across all parts?

A: Yes. OSTED033150, EDZ602/3, and 1727023 all carry ROHS3 compliance and MSL 1 (unlimited) ratings. REACH status is unaffected for all three parts. Regulatory compliance is maintained across all substitution options.
