Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ED655/2DS is determined by the following critical parameters:

Mechanical Compatibility:

• Positions per level: 2 (fixed requirement)
• Pitch: 0.276" (7.00mm) (fixed requirement)
• Mating orientation: Horizontal with Board (fixed requirement)
• Mounting type: Through Hole (fixed requirement)
• Screw thread: M2 (fixed requirement)

Electrical Compatibility:

• Current rating must meet or exceed 6 A
• Voltage rating must meet or exceed 250 V
• Wire gauge range must accommodate 16-28 AWG

Environmental & Compliance:

• Operating temperature range must encompass -30°C ~ 105°C
• RoHS3 compliance required
• REACH Unaffected status required

The substitute part OSTTE021104 meets the mechanical compatibility requirements (2 positions, 7.00mm pitch, horizontal orientation, through-hole mounting, M2 screw). However, electrical ratings differ: OSTTE021104 provides 10 A at 125 V versus ED655/2DS at 6 A at 250 V. Wire gauge acceptance is 16-26 AWG (versus 16-28 AWG). Operating temperature range is -40°C ~ 115°C, which encompasses the ED655/2DS range. Both parts are RoHS3 compliant and REACH Unaffected.

Parameter Comparison

Engineering Selection Recommendations

Both ED655/2DS and OSTTE021104 are Active products with ROHS3 compliance and REACH Unaffected status. Selection between these parts must account for the following electrical parameter differences:

The ED655/2DS is rated for 250 V operation, while OSTTE021104 is rated for 125 V. Applications requiring voltages above 125 V must use ED655/2DS. The ED655/2DS supports wire gauges from 16-28 AWG, while OSTTE021104 accepts 16-26 AWG; applications using 27-28 AWG wire require ED655/2DS. The OSTTE021104 provides higher current capacity (10 A versus 6 A) and extended operating temperature range (-40°C ~ 115°C versus -30°C ~ 105°C). Both parts share identical mechanical specifications: 2 positions, 7.00mm pitch, horizontal orientation, through-hole mounting, and M2 screw thread. Compliance certifications are equivalent for both parts.

Frequently Asked Questions (FAQ)

Q: Can OSTTE021104 replace ED655/2DS in all applications?

A: No. OSTTE021104 has a lower voltage rating (125 V versus 250 V). Applications operating above 125 V require ED655/2DS. Additionally, OSTTE021104 accepts wire gauges 16-26 AWG, while ED655/2DS accepts 16-28 AWG; applications using 27-28 AWG wire must use ED655/2DS.

Q: Are the mechanical dimensions identical between these parts?

A: Yes. Both parts share identical mechanical specifications: 2 positions, 0.276" (7.00mm) pitch, horizontal board orientation, through-hole mounting, and M2 screw thread. PCB footprints are compatible.

Q: What are the key differences in wire termination?

A: ED655/2DS uses standard screw termination. OSTTE021104 includes screw termination with leaf spring and wire guard features, providing additional wire retention and protection.

Q: Are both parts RoHS3 compliant?

A: Yes. Both ED655/2DS and OSTTE021104 are ROHS3 compliant and REACH Unaffected.

Q: Which part has a wider operating temperature range?

A: OSTTE021104 operates from -40°C ~ 115°C, compared to ED655/2DS at -30°C ~ 105°C. OSTTE021104 provides extended low-temperature and high-temperature operation.

Q: What is the difference in screw torque specifications?

A: ED655/2DS requires 0.4 Nm (4.6 Lb-In) screw torque, while OSTTE021104 requires 0.2 Nm (1.7 Lb-In). Different torque values must be applied during assembly.
