RN70D1002FRSL Equivalent & Substitute Parts

Part Overview

The RN70D1002FRSL is a 10 kOhms ±1% metal film through-hole resistor rated at 0.75W (3/4W) in axial package configuration. Manufactured by Vishay Dale, this component is part of the military-grade RN70 series compliant with MIL-R-10509/3 specifications. The part features flame retardant coating, moisture resistance, and safety-rated construction suitable for military and high-reliability applications. With active product status and 872 units in stock, substitute parts may be required due to packaging format availability, inventory constraints, or specific application requirements for alternative temperature coefficient performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN70D1002FRSL is based on electrical and mechanical parameter equivalence within the RN70 military series. The primary substitute, RN70C1002FB14, maintains identical electrical specifications: 10 kOhms resistance, ±1% tolerance, 0.75W power rating, metal film composition, and axial package configuration. Both parts operate across the same temperature range (-65°C to 175°C) and share military-grade construction with flame retardant coating and moisture resistance.

The key differentiator between these parts is packaging format: RN70D1002FRSL is supplied in Tape & Reel (TR) format, while RN70C1002FB14 is supplied in Bulk format. Additionally, RN70C1002FB14 features a tighter temperature coefficient specification (±50ppm/°C) compared to the main part (±100ppm/°C), making it suitable for applications requiring enhanced temperature stability.

Substitution is valid when packaging format flexibility exists and temperature coefficient performance requirements align with the substitute specification.

Parameter Comparison

Engineering Selection Recommendations

Both RN70D1002FRSL and RN70C1002FB14 are active military-grade components within the RN70 series, maintaining full compliance with MIL-R-10509/3 specifications. Selection between these parts depends on application-specific requirements:

RN70D1002FRSL is the primary choice when Tape & Reel packaging is required for automated assembly processes or when the ±100ppm/°C temperature coefficient meets circuit performance specifications.

RN70C1002FB14 is the appropriate substitute when Bulk packaging is acceptable and enhanced temperature stability (±50ppm/°C) is beneficial for precision analog circuits or temperature-sensitive applications. The tighter temperature coefficient provides improved performance in environments with significant thermal variation across the -65°C to 175°C operating range.

Both parts share identical electrical ratings, physical dimensions (0.180" Dia x 0.562" L), two-terminal axial configuration, and military-grade construction features. Substitution is electrically and mechanically valid when packaging format requirements are satisfied.

Frequently Asked Questions (FAQ)

Q: Can RN70C1002FB14 directly replace RN70D1002FRSL in existing designs?

A: Yes, from an electrical and mechanical standpoint. Both components have identical resistance (10 kOhms), tolerance (±1%), power rating (0.75W), package type (axial), and operating temperature range (-65°C to 175°C). The primary difference is packaging format (Tape & Reel versus Bulk) and temperature coefficient specification. If your assembly process accommodates Bulk packaging and the tighter temperature coefficient (±50ppm/°C) does not conflict with circuit requirements, substitution is valid.

Q: What is the significance of the temperature coefficient difference?

A: Temperature coefficient indicates how much the resistance value changes per degree Celsius within the operating range. RN70D1002FRSL has ±100ppm/°C, while RN70C1002FB14 has ±50ppm/°C. The substitute part exhibits half the temperature-induced resistance drift, making it preferable for precision circuits where temperature stability is critical. For general-purpose applications, both specifications are acceptable.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are military-grade components within the RN70 series, compliant with MIL-R-10509/3. Both share identical RoHS non-compliant status, REACH Affected designation, and active product status. Compliance profiles are equivalent.

Q: What packaging format should I specify for my application?

A: Tape & Reel (TR) packaging is standard for high-volume automated assembly and pick-and-place operations. Bulk packaging is suitable for manual assembly, low-volume production, or applications where component handling flexibility is prioritized. Verify your assembly process requirements before selecting between these formats.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both RN70D1002FRSL and RN70C1002FB14 share identical axial package dimensions: 0.180" Dia x 0.562" L (4.57mm x 14.27mm). PCB layout and mechanical clearance requirements are identical.
