OSTED043150 Equivalent & Substitute Parts

Part Overview

The OSTED043150 is a 4-position wire-to-board terminal block manufactured by On Shore Technology Inc., designed for horizontal PCB mounting with 0.150" (3.81mm) pitch spacing. This component features screw-based rising cage clamp termination and is rated for 8A at 300V with wire gauges from 16-24 AWG.

The OSTED043150 carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades.

Substitute Part Grouping Explanation

Substitution eligibility for the OSTED043150 is determined by strict alignment with the following core parameters:

4 positions per level
0.150" (3.81mm) pitch spacing
Horizontal with board mating orientation
Through hole mounting
Screw-based rising cage clamp termination
M2 screw thread
300V voltage rating

Engineering Selection Recommendations

Both EDZ602/4 and 1727036 are qualified substitutes for the OSTED043150 based on electrical and mechanical parameter alignment.

EDZ602/4 is manufactured by On Shore Technology Inc., the original equipment manufacturer of the OSTED043150. This part maintains design continuity with the original supplier and carries active product status with confirmed inventory availability. The EDZ602/4 supports extended wire gauge compatibility (16-30 AWG versus 16-24 AWG) and provides increased current capacity (10A versus 8A), offering enhanced performance margins within the same form factor.

1727036 is manufactured by Phoenix Contact under the COMBICON MKDS series. This part provides the highest current rating (14.6A) among available substitutes and supports the extended wire gauge range (16-30 AWG). The part carries active product status with substantial inventory availability. Both substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the original component.

Frequently Asked Questions (FAQ)

Q: Can EDZ602/4 be used as a direct replacement for OSTED043150 in existing designs?

A: Yes. EDZ602/4 maintains identical pitch spacing (0.150"), position count (4), mating orientation (horizontal with board), mounting type (through hole), and termination method (screw rising cage clamp). PCB footprints are compatible. The substitute supports the same wire gauge range minimum (16 AWG) and voltage rating (300V).

Q: What are the differences in current rating between the substitute parts?

A: OSTED043150 is rated for 8A. EDZ602/4 is rated for 10A. 1727036 is rated for 14.6A. All three parts are suitable for applications within the 8A specification. The higher ratings of the substitutes provide additional design margin without requiring PCB layout modifications.

Q: Are there wire gauge compatibility considerations when substituting?

A: OSTED043150 accepts 16-24 AWG wire. Both EDZ602/4 and 1727036 accept 16-30 AWG wire. This extended range in the substitutes provides greater flexibility for wire selection. Designs using 16-24 AWG wire are fully compatible with both substitutes.

Q: Do the substitute parts meet the same compliance requirements?

A: Yes. OSTED043150, EDZ602/4, and 1727036 are all ROHS3 compliant and REACH unaffected. All three parts carry EAR99 ECCN classification and 8536.90.4000 HTSUS code.

Q: What is the inventory status of these substitute parts?

A: OSTED043150 (obsolete) has 999 pcs in stock. EDZ602/4 (active) has 1018 pcs in stock. 1727036 (active) has 7507 pcs in stock. The active status of the substitutes ensures continued availability for future procurement.

Q: Are there torque specification differences for screw termination?

A: OSTED043150 specifies 0.25 Nm (2.2 Lb-In) screw torque. EDZ602/4 specifies 0.4 Nm (4.6 Lb-In). 1727036 specifies 0.22-0.25 Nm (1.9-2.2 Lb-In). Assembly procedures should reference the specific torque value for the selected substitute part.
