Parameter Comparison

Engineering Selection Recommendations

Both substitute parts 2-1617527-3 and 2-1617003-4 are direct parametric equivalents to the discontinued 1-1617002-8 relay. Selection between these substitutes is based on the following factors:

Product Status: Both substitute parts maintain Active product status, ensuring continued availability and manufacturer support. The original part 1-1617002-8 is discontinued at DiGi Electronics, necessitating transition to one of these active alternatives.

Compliance and Certification: All three parts share identical RoHS non-compliant and REACH Unaffected status, maintaining consistent regulatory positioning across the substitution group.

Inventory Availability: Part 2-1617003-4 offers the highest inventory level at 955 pieces, followed by 2-1617527-3 at 716 pieces. The original part maintains 788 pieces in stock.

Packaging: Both substitute parts are supplied in Bulk packaging, consistent with aerospace and defense component distribution standards.

No technical differentiation exists between the substitute parts based on provided electrical and mechanical parameters. Selection should be based on procurement requirements, inventory availability, and packaging preferences.

Frequently Asked Questions (FAQ)

Q: Can 2-1617527-3 or 2-1617003-4 be used as direct replacements for 1-1617002-8?

A: Yes. Both substitute parts maintain identical electrical specifications, mechanical configuration, and operating characteristics. All critical parameters including coil voltage, contact form, current rating, switching voltage, timing characteristics, and operating temperature range are equivalent.

Q: What is the difference between the two substitute parts?

A: The substitute parts 2-1617527-3 and 2-1617003-4 are parametrically identical. Differences exist only in base product numbers (B07B61 versus B07B93) and inventory levels. Both are manufactured by TE Connectivity Aerospace, Defense and Marine and maintain Active product status.

Q: Are there any compatibility concerns with the packaging format?

A: Both substitute parts are supplied in Bulk packaging. The original part 1-1617002-8 does not specify a packaging format. Bulk packaging is standard for aerospace and defense relay applications and presents no compatibility issues for chassis mount installation.

Q: Do the substitute parts maintain the same compliance status?

A: Yes. All three parts share identical RoHS non-compliant and REACH Unaffected status. Regulatory positioning remains unchanged with either substitute.

Q: What is the basis for substitution equivalence?

A: Substitution is based on complete parametric equivalence across all electrical parameters (coil voltage, contact form, current rating, switching voltage, coil current, coil resistance, operate/release voltages and times, contact material), mechanical parameters (mounting type, termination style, seal rating, operating temperature range), and series designation. All parameters must match for substitution validity.

Q: Why is the original part discontinued?

A: The original part 1-1617002-8 is discontinued at DiGi Electronics. The substitute parts 2-1617527-3 and 2-1617003-4 maintain Active status and provide continued availability for this relay specification.

Q: Can I mix parts from different substitutes in the same application?

A: Yes. Since both substitute parts are parametrically identical, they can be used interchangeably within the same application or system without functional or performance differences.
