PPG101HB RTD Temperature Sensor - Equivalent & Substitute Parts

Part Overview

The PPG101HB is a platinum resistance temperature detector (RTD) manufactured by Littelfuse Inc., designed for precision temperature measurement applications. This sensor features a 100 Ohm resistance at 0°C with Class B accuracy and operates across a wide temperature range from -50°C to 500°C. The PPG101HB is classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PPG101HB is determined by strict equivalence across the following critical parameters:

• Resistance value at 0°C: 100 Ohms
• Resistance tolerance: ±0.12%
• RTD material composition: Platinum (Pt)
• Temperature coefficient: 3850ppm/°C
• Operating temperature range: -50°C ~ 500°C
• Accuracy specification: ±0.3°C
• Mounting configuration: Through Hole with Radial package
• Termination type: PC Pins

The PPG101JB meets all these criteria and is classified as an active product, providing direct functional and electrical equivalence to the obsolete PPG101HB.

Parameter Comparison

Engineering Selection Recommendations

The PPG101JB is the direct equivalent substitute for the obsolete PPG101HB. Both components are manufactured by Littelfuse Inc. within the PPG series and maintain identical electrical and mechanical specifications. The PPG101JB carries active product status, ensuring ongoing availability and manufacturer support. Both parts maintain ROHS3 compliance and identical export classification (EAR99), confirming regulatory equivalence for applications requiring environmental and trade compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can PPG101JB be used as a direct replacement for PPG101HB in existing designs?

A: Yes. The PPG101JB provides complete functional and electrical equivalence. All critical parameters—resistance value, tolerance, temperature coefficient, accuracy, and operating range—are identical. The through-hole radial package and PC pin termination are unchanged, enabling direct board-level substitution.

Q: What is the primary reason for substituting PPG101HB?

A: The PPG101HB is classified as obsolete. The PPG101JB is an active product from the same manufacturer and series, ensuring continued supply chain availability and manufacturer technical support.

Q: Are there any compliance differences between these parts?

A: No. Both components maintain ROHS3 compliance, identical moisture sensitivity level (MSL 1), and the same export classification (EAR99). Regulatory documentation requirements remain unchanged.

Q: Does packaging differ between PPG101HB and PPG101JB?

A: The mechanical package and termination are identical. Both use radial through-hole configuration with PC pins. Packaging format for distribution may differ (the PPG101JB is supplied in bulk), but this does not affect component performance or board integration.

Q: Are there any temperature measurement accuracy differences?

A: No. Both components specify ±0.3°C accuracy across the -50°C to 500°C operating range with identical platinum RTD material and 3850ppm/°C temperature coefficient.
