Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters: 2-position configuration, 4.6mm pitch, horizontal with board mating orientation, through-hole mounting, M2 screw thread, and ROHS3 compliance. All identified substitutes meet these core requirements.

The substitute parts are grouped into two categories based on voltage rating compatibility:

Category A (300V Rated): YO0201500000G maintains the 300V voltage specification of the main part, with rising cage clamp termination and extended wire gauge support (16-24 AWG).

Category B (125V Rated): OSTTE020104 and OSTTE020161 operate at 125V, which is lower than the main part specification. These parts employ leaf spring with wire guard termination and support wire gauges 16-26 AWG.

Engineering Selection Recommendations

All substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the main part.

For applications requiring 300V operation: YO0201500000G (Amphenol Anytek) is the direct voltage-rated equivalent. This part maintains the 300V specification and rising cage clamp termination architecture. Wire gauge support extends to 16-24 AWG, which covers the primary operating range of the main part. Operating temperature range of -40°C to 115°C provides extended thermal performance.

For applications operating at or below 125V: OSTTE020104 and OSTTE020161 (On Shore Technology Inc.) are functionally compatible substitutes. Both parts employ leaf spring with wire guard termination and support wire gauges 16-26 AWG. OSTTE020104 maintains black housing color matching the main part. OSTTE020161 provides blue housing with operating temperature range of -30°C to 105°C. Both parts feature superior MSL ratings (1 vs. 3), indicating lower moisture sensitivity.

Wire gauge compatibility requires verification: applications utilizing 28-30 AWG conductors are not supported by any substitute part and require the main part or custom sourcing.

Frequently Asked Questions (FAQ)

Q: Can OSTTE020104 or OSTTE020161 replace the Phoenix Contact 1985807 in all applications?

A: These parts are compatible for applications operating at 125V or below. Applications requiring 300V operation must use YO0201500000G or the original Phoenix Contact part. Wire gauge compatibility is limited to 16-26 AWG; applications using 28-30 AWG require the main part.

Q: What is the primary difference between OSTTE020104 and OSTTE020161?

A: Both parts are electrically identical with identical wire gauge and voltage ratings. OSTTE020104 features black housing; OSTTE020161 features blue housing. OSTTE020161 has a slightly lower operating temperature maximum (105°C vs. 115°C).

Q: Is YO0201500000G a direct replacement for the Phoenix Contact 1985807?

A: YO0201500000G matches the 300V voltage rating and rising cage clamp termination of the main part. Wire gauge support is 16-24 AWG, which excludes 28-30 AWG applications. Screw torque specification is 0.2 Nm versus 0.22-0.25 Nm for the main part.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance certification, matching the regulatory status of the main part.

Q: What does MSL rating indicate for these terminal blocks?

A: Moisture Sensitivity Level (MSL) indicates the component's sensitivity to moisture during storage and handling. The main part carries MSL 3 (168-hour limit); all substitutes carry MSL 1 (unlimited), indicating superior moisture resistance and more flexible storage conditions.

Q: Can these parts be used interchangeably on the same PCB?

A: Mechanical compatibility is confirmed: all parts share 4.6mm pitch, 2-position configuration, through-hole mounting, and M2 screw thread. Electrical compatibility depends on application voltage requirements. Color differences may affect visual identification on assembled boards.
