Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the TE Connectivity 1-390261-3 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Number of Positions: 14 (2 x 7)
• Type: DIP with 0.3" (7.62mm) row spacing
• Pitch - Mating: 0.100" (2.54mm)
• Pitch - Post: 0.100" (2.54mm)
• Contact Finish - Mating: Tin
• Contact Material - Mating: Phosphor Bronze
• Mounting Type: Through Hole
• Termination: Solder

Acceptable Variation Parameters:

• Operating Temperature Range: Equal to or exceeding -40°C ~ 105°C
• Contact Resistance: Equal to or lower than 30mOhm
• Contact Material - Post: Phosphor Bronze or Brass/Copper
• Termination Post Length: Variations within 0.118" ± tolerance acceptable for through-hole mounting
• Housing Material: Polybutylene Terephthalate (PBT) with glass fill acceptable
• RoHS and compliance certifications: ROHS3 or RoHS Compliant acceptable

The substitute parts listed below maintain all critical matching parameters while offering improved specifications in contact resistance, operating temperature range, and material flammability ratings.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Highest Compatibility):

The TE Connectivity 1-2199298-3 and On Shore Technology ED14DT are direct substitutes for the obsolete 1-390261-3. Both components maintain identical electrical and mechanical specifications while offering active product status and improved contact resistance (20mOhm versus 30mOhm). The 1-2199298-3 is part of the Diplomate DL series and carries RoHS compliance certification. The ED14DT extends the operating temperature range to -55°C ~ 110°C and provides ROHS3 compliance with REACH Unaffected status.

Similar Substitutes (Acceptable Compatibility):

The CNC Tech 243-14-1-03 and Adam Tech ICS-314-T are similar substitutes that maintain all critical electrical and mechanical parameters. Both components feature improved contact resistance (20mOhm), UL94 V-0 flammability ratings, and active product status. The 243-14-1-03 maintains the original operating temperature range of -40°C ~ 105°C with a termination post length of 0.124" (3.15mm). The ICS-314-T extends the lower operating temperature to -55°C and provides REACH Unaffected certification.

Compliance Considerations:

All substitute parts maintain ROHS3 or RoHS compliance and MSL 1 (Unlimited) moisture sensitivity ratings, ensuring compatibility with modern manufacturing and environmental standards. The ED14DT and ICS-314-T provide extended operating temperature ranges suitable for applications requiring enhanced thermal performance.

Frequently Asked Questions (FAQ)

Q: Can the 1-2199298-3 be used as a direct replacement for the 1-390261-3?

A: Yes. The 1-2199298-3 maintains identical electrical and mechanical specifications including 14-position configuration, 0.3" row spacing, 0.100" pitch, tin-plated phosphor bronze contacts, and through-hole solder termination. The substitute offers improved contact resistance (20mOhm versus 30mOhm) and active product status.

Q: What is the difference between direct and similar substitutes?

A: Direct substitutes (1-2199298-3 and ED14DT) are manufactured by TE Connectivity and On Shore Technology respectively, with specifications matching the original part. Similar substitutes (243-14-1-03 and ICS-314-T) are manufactured by alternative suppliers (CNC Tech and Adam Tech) and maintain all critical parameters while offering variations in termination post length and operating temperature ranges.

Q: Are there any compatibility issues with the termination post length variations?

A: No. The termination post length variations (0.118" for the main part, 0.124" for 243-14-1-03 and ICS-314-T) are acceptable for through-hole solder mounting applications. Both lengths accommodate standard PCB hole spacing and solder joint formation.

Q: Which substitute offers the widest operating temperature range?

A: The ED14DT and ICS-314-T both extend the operating temperature range to -55°C ~ 110°C and -55°C ~ 105°C respectively, compared to the original -40°C ~ 105°C specification.

Q: Do all substitutes meet RoHS compliance requirements?

A: Yes. All substitute parts carry either ROHS3 or RoHS compliance certification, meeting current environmental and regulatory standards.

Q: What is the inventory availability for each substitute?

A: The 1-2199298-3 has 8,621 pieces in stock, ED14DT has 9,199 pieces, 243-14-1-03 has 4,486 pieces, and ICS-314-T has 2,875 pieces available as new original stock.

Q: Can substitutes be mixed in the same assembly?

A: Yes. All substitute parts maintain identical electrical and mechanical specifications for the critical mating interface (14 positions, 0.100" pitch, tin-plated phosphor bronze contacts), allowing interchangeability within the same assembly.
